Practice Calibration

Use this after attempting independent practice. These are calibration notes for the new cases, not answers to every original open-ended project. The module assessment retains its own scoring and evidence requirements.

Prerequisite calibration

Revision, artifact, command/environment, inputs, result and the claim tested. Repair reproducibility and review evidence.

A ready answer includes the example or trace requested in the entry check. A memorized term is not sufficient. Repair the named earlier skill, then change the example and explain it without this page.

Case A

Identify the workload mismatch and claimed consequence. Ask for representative conditions or narrow the decision; distinguish absent evidence from proof that the database cannot work.

Full practice credit requires the result, assumptions and an explanation of the tempting error. A correctly guessed conclusion without those elements is only partial evidence.

Case B

Preserve the original decision context, link the new evidence and superseding decision, and record owner/trigger/date. Do not rewrite history to imply the evidence was known earlier.

The key judgment is which guarantee survives the changed condition. Do not transfer a result from the first case without checking that condition.

Experiment calibration

Use the proposal-review kit and one actual or explicitly labeled solo architecture review. Preserve alternatives, prioritized findings, decision owner and a revisit trigger; generated summaries do not replace reviewed artifacts.

A usable record links the hypothesis to the actual input, observation and interpretation. The negative control must fail for the intended reason, and the repaired setup must pass the relevant check again. Report unexpected outcomes rather than altering the hypothesis afterward. Explicitly state the model, environment and untested boundary; passing a small fixture never proves every deployment behavior.

Recheck

Explain a fresh variant without the key. Retain the original error, repair, help received and delayed result in the existing evidence packet. Self-calibration is not an independent reviewer sign-off or a learner-pilot result. For retrieval-question explanations, use quiz calibration only after attempting the quiz.
